    LabLab

    6 lab sessions

    Demonstrations and assignments

    - We will mostly use MATLAB

    ExamExam

    Written test

    - 80% of the final score

    - Numerical exercises- Theoretical questions

    - You can get 24/30 with written test

    M.M. Poncino - Politecnico di Torino 7

    Lab attendance is mandatory

    - Assignments will be evaluated and will give extra scores

    (up to 9 = 1.5*6 points)

    ProjectsProjects

    On demand:You can apply for projects to get with extra score

    Two types of projects

    - Type 1: SMALL projects Effort = 1 week full time (~40 hours/person)

    M.M. Poncino - Politecnico di Torino 8

    - Type 2: LARGE projects:

    Effort = ~2 weeks full time (~100 hours/person)

    Up to 6 extra points

    Natural evolution into a thesis

    What this course is (not)What this course is (not)

    Main objective is understanding the secrets ofpowerefficient design

    - With emphasis on embedded systems (with all what that means),e.g.:

    We can spend performance to buy power

    We can exploit domain- and application-specific information

    M.M. Poncino - Politecnico di Torino 9

    typ ca y, t e wor oa

    We should consider that most embedded systems are battery-powered devices

    This course is not- A design course in terms of programming a platform/board

    - A course where you will build or use prototypes
